More evidence that this is a golden age for animation, especially with the perfecting of computer-animation techniques. But Zootopia's success lies as much in its story and its voice actors as in its technology. Actually, the success of the story is a bit of a surprise, considering that it was created by a committee and went through many alterations before settling on the central thread of a young rabbit, Judy Hopps (voice of Gennifer Goodwin), who wants to be a cop, and eventually teams up with a con-man fox, Nick Wilde (voice of Jason Bateman), to solve the mysterious disappearances of several residents of Zootopia, a place where predators and prey have learned to live together amicably. It seems that the disappeared were all predators who "turned feral" before they vanished. No fewer than seven credited writers -- and doubtless many more uncredited -- worked on the story before it was turned into a screenplay by Phil Johnston and Jared Bush (the latter also receives a credit as "co-director," whatever that means). Goodwin and Bateman are full of charm in their line delivery, and Idris Elba, as Judy's blustering and bellowing police chief, brings great energy to his role. Like so many recent computer-animated features, it is sometimes over-crowded with gags taking place on the periphery that it's possible to get a little distracted by them: a sure way of enticing people to watch the movie more than once.
